Golden Finance reported that Paradigm-backed startup Succinct Labs announced on Wednesday that it has been working with OP Labs, a major contributor to the Optimism protocol, to "solve" the problems of ZK Rollups. "Over the past few months, we have worked closely with the OP Labs team to build OP Succinct, a seamless way to upgrade any OP Stack chain to use zero-knowledge proofs within 1 hour." Succinct Labs raised $55 million in seed and Series A funding led by Paradigm in March this year. The company said its new method is much faster than "standard optimistic rollups", which has a "7-day fraud proof window" and costs only "a few cents" per transaction on average.
